Acrobits Softphone fans, please rate Acrobits Softphone or leave a review.

If you have an issue with Acrobits Softphone, please contact our support even if you leave a review stating the problem. We are unable to respond to reviews so even if your issue is simple to resolve, we have no way of letting you know. Acrobits Softphone is highly configurable so problems that seem insurmountable may just require a couple of adjustments to the settings.

Acrobits Softphone has more options for receiving calls when not in the foreground than any SIP Client on the App Store.  But since they all work very differently, we don't turn them on by default.  Check out http://www.acrobits.cz/hesk/knowledgebase.php?article=53 for a comparison of the options available.


SIP - Acrobits Softphone is a SIP Client, not a VoIP service. You must have service with a VoIP provider that supports use on a standard SIP client to use it.


VoIP over 3G - Be aware that some mobile operators prohibit or restrict the use of VoIP over their network. They may prohibit the use of VoIP or impose additional fees when using VoIP over their network. By using the app over 3G, you agree to abide by any restrictions your cellular carrier imposes and agree that Acrobits will not be held responsible for any fees or liability imposed by your carrier for using the app over 3G network.

What's New in Version 5.8.3

- correct way to disable CallKit support
- allow system ringtones for CallKit calls
- fixed: incoming VP8 video was broken on "plus" devices
- fixed: when switching contact sorting order from "first-last" to "last-first", the sections were wrong

Best Softphone Available!

I have used various softphone apps, Acrobits is the best! It is very easy to use, most providers are already set up so all you do is enter your username and password. I wish it was this easy on my desk phone.

The ability to have multiple accounts signed in at the same time is a great feature!

This app has more features than my $300 desk phone and it works anywhere.

Push notifications allow me to receive calls without draining my battery.

I was a little hesitant about this app because of the price but it is the most used app on my iPhone. If you need a softphone app, this is definitely the best available.

5/5 stars
